1.Chewing and saliva break down <-- START
->(makes mushy and easy to swallow) (mushed up food called bolus)
2. bolus goes to esophagus
-> stretchy pipe (10 inches/25 cm long)
-> epiglottis covers windpipe when you eat so you dont choke
3. muscles in esophagus squeeze bolus down to the stomach
-> takes 2 -3 sec.
4. stomach -stores food
- break down food even more (by squishing from walls & gastric juices/acid)
- slowly empty food into small intestines
- kill unwanted bacteria in food
5. small intestine breaks down food to absorb its good stuff
-> vitamins, minerals, carbs and fats (energy/nutrients) to be absorbed in bloodstream
-> has help from 3 friends (psncreas, liver and gallbladder)
-> 3.5-5 cm diametre and 6.7 metres longhttp://www.healerwithin.org/IMLS/Gr2_digestion.pdf-> up to 4 hours in small intestine
6. nutrients go into liverhttp://www.healerwithin.org/IMLS/Gr2_digestion.pdf7. leftover waste from food goes to large intestines
->7 cm diametre and 1.5 metres in length
8. at the end of large intestine, reaches colon
->last chance to absorb water and nutrients
waste (poo(p)) also called 'bowel movement'
9. rectum, where it is stored before you go to the washroom <-- END
